Understanding Czech AIFC files
Czech has a notable gap between the written standard (spisovná čeština) and the everyday spoken variety known as Common Czech (obecná čeština), which dominates casual speech in Bohemia. Moravian and Silesian regional dialects add further variation, and Czech is closely related to — but distinct from — Slovak, so recordings should be matched to the correct language.

Frequently asked questions
How to improve the accuracy of your Czech transcripts?
Start by improving the quality of the Czech AIFC file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Czech AIFC file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Czech AIFC file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from AIFC, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Czech with Sonix:
Why won't my AIFC file play on Windows?
Many Windows applications lack decoders for the compression codecs AIFC can contain, such as µ-law, A-law, and G.722. Converting the file to WAV or MP3, or uploading it to a service that decodes AIFC, works around this.
Do I need to convert AIFC to WAV before transcribing?
No. AIFC files can be uploaded directly and are decoded automatically before transcription, so a separate conversion step is not required.
Can Sonix transcribe Czech audio and video files?
Yes. Upload your Czech audio or video file, select Czech as the spoken language, and Sonix returns a transcript you can edit in the browser and export to formats like Word, SRT, and VTT.
Does Czech transcription handle Moravian dialects and colloquial Czech?
Czech speech recognition is built around standard Czech, so regional dialects and colloquial Common Czech forms may need review. The Sonix editor syncs text to audio, making it straightforward to check and correct dialect passages.
Should I choose Czech or Slovak for a mixed recording?
Czech and Slovak are separate language selections in Sonix, so choose the language most of the recording is spoken in. For conversations that switch between the two, transcribing each file under its dominant language gives the cleanest starting point.
